NEED DRIVER! Support Elan Microelectronics Corp. ELAN:ARM-M4

[iNeedIT]

Hello folks!

Like in subject, I am having a big trouble with USB device, namely fingerprint sensor from Elan.

I researched a half of internet, but it look like there is driver for it!
Link: https://linux-hardware.org/?id=usb:04f3-0c4c

Badly for us, because gentoo fprint library does not have these a drivers, yet...
And question is here. How exactly install it on gentoo [n00b queston, I know]
It seems, arch repository include elan drivers. Can I use package from pacman for gentoo?
It is here another way to have sensor? Maybe from different source?
I don't have big brain to create own driver.

Please, bump that post. We can gather drivers for those in need.
